mxImageBundle

Maps from keys to base64 encoded images or file locations. All values must be URLs or use the format data:image/format followed by a comma and the base64 encoded image data, eg. “data:image/gif,XYZ”, where XYZ is the base64 encoded image data.

$bundle = new mxImageBundle();
$bundle->putImage("myImage", "data:image/gif,R0lGODlhEAAQAMIGAAAAAICAAICAgP".
  "//AOzp2O3r2////////yH+FUNyZWF0ZWQgd2l0aCBUaGUgR0lNUAAh+QQBCgAHACwAAAAAEA".
  "AQAAADTXi63AowynnAMDfjPUDlnAAJhmeBFxAEloliKltWmiYCQvfVr6lBPB1ggxN1hilaSS".
  "ASFQpIV5HJBDyHpqK2ejVRm2AAgZCdmCGO9CIBADs=");
$graph->addImageBundle($bundle);
(end);

The image can then be referenced in any cell style using image=myImage.

To convert an image at a given URL to a base64 encoded String, the following
code can be used:

(code)
echo "base64=".base64_encode(file_get_contents($url));

The value is decoded in mxUtils.loadImage. The keys for images are resolved and the short format above is converted to a data URI in mxGraph.postProcessCellStyle.
